Definitions
- This invention relates to methods for controlling the reel-up operation of paper webs, particularly in Pope-type reel-up apparatus.
- Pope-type reel-up apparatus include a reeling cylinder by which power is provided to a web reel being formed on a reeling drum through a nip formed between the periphery of the reeling cylinder and the periphery of the web reel being formed.
- the inner section of the web reel is formed on the reeling drum which is held on primary forks or the like whereupon the reeling drum and section of the web reel formed thereon are removed to secondary forks on which the final steps of the reeling operation are carried out.
- the loading of the power-transmitting nip is at least mainly provided by power equipment coupled to the primary and secondary forks.
- Pope-type reel-up apparatus are commonly used for reeling paper web from equipment such as paper machines, coating machines, supercalenders and printing machines.
- the web is reeled onto a drum and the web reel being formed is pressed against a Pope-type or reeling cylinder over a sector of which the web runs and which rotates at a peripheral speed which corresponds to the desired web speed.
- a new reeling drum may be brought into nip contact with the Pope cylinder after the reeling is accellerated to the proper running speed.
- the web reel attains the desired diameter, it is separated from the Pope cylinder so that its rotational speed decreases causing a web loop to form between the new reeling drum and the completed web reel.
- This loop is guided such, for example, as by means of a compressed air jet, to be wound around the new reeling drum whereupon the web is torn from the completed web reel.
- the main reason for the formation of such folds or wrinkles in the inner layers of the web reels is the variation of hardness or density in the bottom part of the reels which, in general, is caused by uncontrolled variations of the linear loading at the nip formed between the paper reel and the Pope cylinder and, additionally, by variations of the tightness of the paper web as discussed below.
- the nip-loading forces provided by the power equipment coupled to the primary and secondary forks which support the reeling drum on which the web reel is wound is controlled by signals determined by the position of the forks in a manner such that the force distribution present in the nip is controlled even during the exchange step in which the reeling drum and paper reel being formed around it is moved from the support and loading of the primary forks to the support and loading of the primary forks to the support and loading of the secondary forks.
- An advantage of the method of control of the invention relative to conventional methods of control is that in accordance with the invention, the exchange step is made to be more reliable than has been possible heretofore.
- the paper web may be removed from the completed paper reel onto an empty reeling drum set up in the exchange position using conventional techniques.
- a typical feature of all exchange operations is that the reliability of the exchange is improved with the number of breaks which occur during the exchange being reduced, if the linear loading between the reeling drum and the reeling cylinder is substantially even or somewhat higher in the middle section of the web than in the edge sections.
- the linear loading and transverse load distribution can be adjusted as desired at the very moment when the web is exchanged from one drum to another by using unloading cylinders acting on the primary forks as described below.
- FIG. 1 is a schematic side elevation view of a Pope-type reel-up apparatus in which a method in accordance with the invention can be used;
- FIG. 2 is a schematic side elevation view of a Pope-type reel-up apparatus in an initial reeling phase and including a block diagram of a control system for performing a method in accordance with the invention
- FIG. 3 is a schematic side elevation view of a Pope-type reel-up apparatus at a stage in which the reeling drum and the inner section of the web reel being formed thereon are moved to a position wherein the same are supported by the secondary forks;
- FIG. 4 is a graphical illustration of a load distribution of a Pope-type reel-up apparatus showing the load in the primary forks and in the secondary forks wherein no unloading systems or special controls in accordance with the present invention are utilized;
- FIG. 5 is graphical illustration of the load distribution of Pope-type reel-up apparatus as a function of time when a control system and method in accordance with the invention are utilized.
- FIG. 6 is a graphical illustration illustrating the load components of the primary and secondary forks, and a combination thereof, which result in the load distribution graphically illustrated in FIG. 5.
- paper web reel-up apparatus are illustrated wherein a reeling cylinder, i.e., a Pope cylinder, 10 provides operating power to the periphery of a web reel R 0 being formed on a reeling drum 11' by a friction nip N (FIG. 2) formed between them.
- the initial stage of the reeling operation is shown with the reeling drum 11' in the position shown in FIG. 2 wherein the reeling drum 11' is supported in and loaded by the primary forks 15 and 16.
- the primary fork 16 is guided on guide bars 14 for movement towards and away from fork 15.
- the primary forks 15 and 16 and guide bars 14 turn downwardly in the direction of arrow A (FIG.
- the paper web entering the reel-up apparatus is designated W in in FIGS. 1-3.
- the reeling drum 11 and paper web being wound thereon lie and rotate on reeling rails 12 while the secondary forks 13 press the drum 11 and paper web R 1 formed thereon against the reeling cylinder 10 as seen in FIG. 3.
- the secondary forks 13 also function to separate the paper reel R from the reeling cylinder 10 when the diameter of the paper reel R reaches its desired value.
- the completed paper reels R are carried by cranes for further processing. Empty reeling drums are then stored on storing rails (not shown) installed over the supporting rails 12.
- the guide bars 14 of the reeling-drum exchange apparatus extend upwardly from the sides of the reeling cylinder 10 and are pivoted at their bottom ends in suitable bearings.
- the reeling drum 11' is held at its respective ends within a gap formed between the bottom primary fork 15 which is fixed on the guide bars 14 and the top primary fork 16 which is movably mounted on the guide bars 14.
- the reel-up apparatus includes loading equipment which in the illustrated embodiment comprises power cylinders 17, 18 and 19, the latter acting on the opposite ends of the reeling drums 11.
- the loading cylinders 17, 18 and 19 may be either pneumatic or hydraulic cylinders or other conventional power units which operate by pressurized medium or in some cases by electricity. In the latter case, the pressures P 0 , P 1 and P 2 referred to below will be understood as corresponding to analogous electrical quantities.
- a conventional Pope-type reel-up apparatus the exchange of a reeling drum is carried out by lifting the reeling drum 11' by a crane over the bottom primary fork 15 and the top primary fork 16 is lowered from a position 16' (FIG. 1) to the position 16 to load the reeling drum 11'. Thereafter, the reeling drum is accelerated with a separate preliminary starting device (not shown) to a rotational speed which is as close as possible to the rotational speed of the periphery of the reeling cylinder 10.
- the guide rails 14 are pivoted in the direction of rotation of the reeling cylinder 10 whereupon the distance between the reeling drum 11' and the reeling cylinder 10 is reduced due to the eccentric mounting of the guide rail 14, to the point where the drum 11' contacts the paper web W which runs on the top of the reeling cylinder 10.
- the reeling drum then starts rotating at precisely the same speed as the reeling cylinder.
- the weight of the reeling drum 11' and the load created by the top fork 16 are at this point removed from the bottom fork 15 to the reeling cylinder 10 whereupon the web W can be exchanged onto the new drum as described above.
- FIG. 2 the stage of the reeling-up operation wherein a paper web W in has just been moved from a completed reel R to an empty reeling drum 11' is illustrated.
- the reeling drum 11' is located against the reeling cylinder 10 under its own weight in combination with the loading forces provided by the twin-loading cylinders 17 of the primary forks 15 and 16.
- the reeling drum 11' begins to decend from the position shown in FIG. 2 in the direction of arrow A.
- the angle a 1 defined between the vertical and the guide rails 14 increases.
- the loading due to the weight of the reeling drum 11' and the inner section of the web reel R 0 becomes smaller as seen by the curve portion designated P' 1 in FIG. 4.
- unloading cylinders are used for maintaining an even loading through reductions in their pressure.
- the loading of the nip N has, in the case of conventional reel-up apparatus, been as shown by the curved section P' 3 of FIG. 4.
- the reeling drum 11 moves on to the reeling rails 12, the angle a 2 formed between the secondary forks 13 and the vertical changing during operation.
- the linear loading P' 3 of the nip N has varied considerably thereby contributing to the drawbacks described above.
- the steps of the reeling operation are divided into three stages, namely,
- a pressure P 0 of the loading cylinders 17 of the primary forks 14, 15 and 16 is maintained substantially constant (the same pressure P 0 being maintained in both cylinders of a twin-cylinder unit).
- the position of the reeling drum 11', shown in FIG. 2 on the periphery of the Pope cylinder 10, i.e., angle a 1 is measured and the pressure P 1 of the unloading cylinders 19 is changed in a manner to obtain a linearly descending curve P 0 -P 1 as seen in FIG. 6 in the section designated I.
- the pressure of the unloading cylinders 19 can also be adjusted in accordance with the value of the angle a 1 .
- the pressure P 1 of the unloading cylinders 19 is controlled to substantially zero or at least to a relatively low level, whereupon the pressure P 0 of loading cylinders 17 is reduced essentially linearly during a time period t 0 to a substantially zero value, the time period being, for example, about 10 seconds.
- the pressure P 2 of the loading cylinders 18 of the secondary forks 13 is raised substantially linearly to a certain initial value P a . Therefore, during the exchange step II, the total load (P 0 +P 2 -P 1 ) will be obtained as shown by the dotted line in the curve section II of FIG. 6 which is seen to be a substantially constant value P a .
- the spike region P' 2 of FIG. 4 and the consequent drawbacks thereof are eliminated.
- the angle a 2 is measured and the pressure of the loading cylinders 18 of the secondary forks 13 is adjusted in accordance with the measuring signals f 2 (FIG. 2) in a manner such that the pressure P 2 of nip N descends in a substantially linear manner as the diameter of the web reel R 1 increases.
- the pressure of the loading cylinder 18 can also be adjusted in any other manner so as to descend substantially linearly.
- the steps I, II and III of the reeling operation produces a loading distribution P(t) of the reeling nip N which descends or otherwise changes in a substantially even manner without any spike as a function of the reeling time t and the radius of the web reel.
- a novel feature of the invention is that a sort of "flexible exchange” is obtained when removing the web reel from the primary forks 15, 16 to the secondary forks 13, i.e., during the controlled exchange step II described above.
- FIG. 2 An embodiment of a control system for performing a method in accordance with the invention is illustrated in FIG. 2 in block diagram form. In embodiments in practice, the control equipment may differ considerably from that shown in FIG. 2.
- a control system in accordance with the invention comprises a central unit 20 which may comprise in practice several separate devices.
- the unit 20 is controlled by a programmable control logic 21 or some other similar system, such as one based on microprocessors.
- the control system comprises conventional sensor devices 22 and 23, sensor device 22 measuring the position of the primary forks 14, 15 and 16, i.e., the angle a 1 , while the second sensor device 23 measures the position of the secondary fork 13, i.e., the angle a 2 .
- Sensors 22 and 23 generate measuring signals f 1 and f 2 which are conducted to the central unit 20 which transmits adjusting signals S 0 , S 1 and S 2 to pressure regulating valves 25, 26 and 27 which control pressures P 0 and P 1 transmitted from pressure sources 24 to loading cylinders 17 of the primary forks 14, 15 and 16 and to unloading cylinders 19 of the primary forks, as well as pressure P 2 directed to loading cylinders 18 of the secondary forks.
- control signals f 1 and f 2 control pressure P 0 , P 1 and P 2 according to a program set by means of the control logic 21 in a manner such that a "smooth" loading distribution curve P(t) as shown in FIG. 5 or the like is obtained.
